Pakistan is a very, very vital problem: Trump

A nuclear-armed Pakistan is a "very very vital problem", Republican presidential front- runner Donald Trump has said and asserted that the country needs to "get a hold of" its situation.

"Pakistan is a very, very vital problem and really vital country for us because they have a thing called nuclear weapons. They have to get a hold of their situation," Trump told CNN during a town hall in Wisconsin, where the Republican presidential primary is scheduled for April 5.

"When I see that and when I see it put in a park because it was mostly Christians, although many others were killed other than Christians, I think it's just absolutely a horrible story," he said referring to the terrorist attack in lahore on Easter Sunday that claimed 74 lives and injured over 300 others.

"I'm talking about radical Islamic terrorism. I will solve it far better than anybody else running," Trump said in response to a question.

A large number of people were present at the crowded Gulshan-e-Iqbal Park of Allama Iqbal Town in lahore when a powerful blast took place on Sunday. A large number of Christian families were present in the park due to Easter Sunday.

The brutal attack by a suicide bomber -- believed to be in his 20s -- was claimed by the Jamaatul Ahrar, a splinter group of the Tehrik-i-Taliban Pakistan (TTP).
